Re: Interesting fine print The trickiest matter on deploying PLC LANs is qualifying the wiring systems and equipment running on top of it, as you are eluding to (it reminds me of the access segment  ). I did put a posting on this topic several months ago looking for UPS and Surge Protection Vendors that would interwork with PLC LANs. There was very little interest on the BBR networking forum (or from Vendors I invited to respond); UL certification of such equipment is also an issue. Note that many UPS do not have an isolation transformer and will let these frequencies through. I have found one Vendor of PowerSurge equipment that will let the PLC LAN frequencies through. Controlling this kind of equipment in someone else premise in the immediate neighborhood is however not an easy matter. The promised "reach" of the PLC LAN to all AC outlets has definitely been overblown and likely hindered deployment of these LANs thus far. |
